In the first stages of Primary, we are learning about what is a living thing and what is not. We are making some murals in the classroom for that.
Science and English teachers reccommend you to enter into this web page http://www.oxfordowl.co.uk/ and register for free.
There you will find e-books for children of these ages with activities related to the concrete reading. These books are good strategies to learn and improve the English of our little ones.
Do not be afraid and read an English book with your children! =)
